Echeveria plant named ‘Calypso’

ABSTRACT

A new and distinct  Echeveria  cultivar named ‘Calypso’ is disclosed, characterized by concentric rosettes comprised of an abundance of ruffled blue-green leaves with crispate margins. The new cultivar is robust growing, quickly filling an 8 inch commercial pot and produces offsets at an early maturity. Plants have been shown to be durable with good landscape performance. Inflorescences are produced in the Summer, comprised of glaucous coral colored flowers.  Echeveria  is a popular genus, typically produced as container plants for the patio or as landscape plants, as a variety of ornamental purposes.

Latin name of the genus and species: Echeveria hybrid.

Variety denomination: ‘CALYPSO’.

BACKGROUND OF THE INVENTION

The new cultivar, Echeveria ‘Calypso’, is the product of a planned breeding program. The new variety originated from a cross pollination of the proprietary, unpatented, seed parent, Echeveria ‘BF II’ with the pollen parent an unpatented, proprietary variety of Echeveria referred to as ‘Val’. The cross pollination was made during May of 2013 in Vista, Calif., at a commercial greenhouse. The new cultivar ‘Calypso’ was discovered by the inventor, Renee O' Connell, in April of 2014, in Vista, Calif. at a commercial greenhouse.

Asexual reproduction of the new cultivar ‘Calypso’ was first performed in Vista, Calif., at a commercial greenhouse, by terminal vegetative cuttings in May of 2014. Echeveria ‘Calypso’ has since produced multiple generations and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘Calypso’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘CALYPSO’. These characteristics in combination distinguish ‘CALYPSO’ as a new and distinct Echeveria cultivar:

-   1. The rosettes of Echeveria ‘Calypso’ are comprised of many ruffled     blue-green leaves, arranged in an attractive concentric rosette, as     compared to many Echeveria cultivars used for larger pot sizes which     produce rosettes with less leaves, and often of a less saturated     shade of blue gray. -   2. Echeveria ‘Calypso’ grows to a diameter of 14″ or more, often     producing offsets to form clusters at approximately 7″ of diameter -   3. The leaves of Echeveria ‘Calypso’ are a rich blue green color,     and display undulate, crispate pink margins, creating an attractive     an attractive contrast between leaf color and the margin color. -   4. A single cut of Echeveria ‘Calypso’ readily fills an 8″ pot,     thereby reducing the number of cuttings required to fulfill a grow     schedule for a 8″ pot in a commercial production setting. -   5. Echeveria ‘Calypso’ produces inflorescences during the summer,     with individual flowers a glaucous coral in color, with inner golden     tangerine tips, flaring outward apically, and becoming orange     basally. -   6. Echeveria ‘Calypso’ is a moderately fast grower, enhancing     production times in the commercial nursery environment. -   7. Echeveria ‘Calypso’ is robust plant, and as such, has proven     durable in the landscape environment.

PARENTAL COMPARISON

Plants of the new cultivar ‘Calypso’ can be compared to plants of the unpatented, proprietary seed parent Echeveria ‘BF II’, and are similar in most horticultural characteristics. However, plants of the new cultivar ‘Calypso’ differ in the following:

-   1. Echeveria ‘Calypso’ forms rosettes that are flatter in morphology     than those of Echeveria ‘BF’ II’. -   2. Echeveria ‘Calypso’ exhibits leaves that are a rich blue-green     color, whereas the leaves of Echeveria ‘BF II’ are a glaucous powder     blue. -   3. Echeveria ‘Calypso’ forms flowers that are glaucous coral in     color, with inner golden tangerine tips, flaring outward apically,     and becoming orange basally, whereas the flowers of Echeveria ‘BF     II’ express a two-toned appearance, coral basally, and golden yellow     apically. -   4. Echeveria ‘Calypso’ displays leaves that are slightly wider than     those of Echeveria ‘BF II’, becoming wider and blunter apically than     those of Echeveria ‘BF II’. -   5. While both Echeveria ‘BF II’ and Echeveria ‘Calypso’ display     undulate, crispate leaves, the leaves of Echeveria ‘Calypso’ differ     additionally in the apical aspect in that they are ‘truffly’,     whereas the apical portion of the leaves of Echeveria ‘BF II’ is     apiculate.

Plants of the new cultivar ‘Calypso’ can be compared to plants of the unpatented, proprietary pollen parent Echeveria ‘Val’, and are similar in most horticultural characteristics. However, plants of the new cultivar ‘Calypso’ differ in the following:

-   1. Echeveria ‘Calypso’ displays rosettes comprised of many rich     blue-green leaves, whereas Echeveria ‘Val’ produces rosettes of     darker blue, tinged with violet in strong light. -   2. Echeveria ‘Calypso’, begins to offset at approximately 6-7″ of     diameter, whereas Echeveria ‘Val’ is reticent to offset. -   3. The flowers of Echeveria ‘Val’ are slightly larger than those of     Echeveria ‘Calypso’, and whereas the flowers of Echeveria ‘Calypso’     are glaucous coral in color, with inner golden tangerine tips,     flaring outward apically, and becoming orange basally, the flowers     of Echeveria ‘Val’ are light gold and do not flare appreciably at     the apex.

COMMERCIAL COMPARISON

The new cultivar ‘Calypso’ can be compared to the unpatented commercial variety Echeveria ‘Afterglow’. Plants of the Echeveria ‘Afterglow’ are similar to plants of the new cultivar ‘Calypso’ in most horticultural characteristics. However, the new cultivar ‘Calypso’ differs in the following:

-   1. Echeveria ‘Calypso’ forms rich blue green rosettes, whereas the     rosettes of Echeveria ‘Afterglow’ are violet in color. -   2. Echeveria ‘Calypso’ exhibits spatulate leaves that are wider at     the tip, whereas the leaves of Echeveria ‘Afterglow’ are more or     less lanceolate in shape, and display little to no crispate margins. -   3. Echeveria ‘Calypso’ displays flowers that are glaucous coral in     color, with inner golden tangerine tips, flaring outward apically,     and becoming orange basally, whereas the flowers of Echeveria     ‘Afterglow’ are a solid orange in color.

The new cultivar ‘Calypso’ can be compared to the unpatented commercial Echeveria subrigida. Plants of Echeveria subrigidas are similar to plants of the new cultivar ‘Calypso’ in most horticultural characteristics. However, plants of the new cultivar ‘Calypso’ differ in the following:

-   1. Echeveria ‘Calypso’ produces rosettes of a rich blue green color,     whereas the rosettes of Echeveria subrigida are a pruinose blue or     near white. -   2. Echeveria ‘Calypso’ produces rosettes of many leaves, whereas     Echeveria subrigida produces rosettes with less leaves. -   3. Echeveria ‘Calypso’ produces more compact rosettes than does     Echeveria subrigida. -   4. Echeveria ‘Calypso’ displays wider, more apically rounded leaves     as compared with the longer leaves produced by Echeveria subrigida,     in conjunction to the more compact morphology of Echeveria     ‘Calypso’, thereby rendering it much less prone to leaf breakage     when shipping specimens. -   5. Echeveria ‘Calypso’ displays flowers that are glaucous coral in     color, with inner golden tangerine tips, flaring outward apically,     and becoming orange basally, whereas the flowers of Echeveria     subrigida are a monotone golden orange in color.
